Résumé

The Internet of Things (IoT) has experienced exponential growth across healthcare, agriculture, transportation, and manufacturing sectors, with the number of connected devices projected to reach 29 billion by 2030, simultaneously creating new avenues for cybercriminal activities and unprecedented challenges for digital forensic investigators. This paper provides a comprehensive analysis of the current state of IoT forensics, examining the specialized techniques, tools, and methodologies required to extract, analyze, and preserve digital evidence from IoT devices. Through a qualitative synthesis of 29 recent peer-reviewed studies, key impediments to effective IoT forensic investigations uncovered by this review include device diversity, the absence of uniform technical standards, restrictions in device resources, the ephemeral character of data, and unresolved legal and ethical dimensions surrounding privacy and multi-jurisdictional evidence handling. A concrete finding from this review is that only 3 of the 29 examined studies reported any form of empirical validation in real-world IoT environments. This reveals that most existing IoT forensic frameworks remain theoretical rather than applied, with significant gaps in evidence collection and pre-processing methodologies. This paper acknowledges that its recommendations similarly lack empirical validation, reflecting a broader field-wide challenge rather than a limitation unique to any single study. Nevertheless, this paper recommends the development of standardized forensic frameworks incorporating artificial intelligence and blockchain technologies, mandatory forensic readiness in IoT device design, and enhanced cross-disciplinary collaboration between computer scientists, legal experts, and law enforcement agencies.
